CAR.

Specification of Letters Patent.

Patented Dec. 24, 1907'.

Application filed February '7, 1907. Serial No. 356.176.

To all whom it may concern:

' Be it known that I, EZRA S. BUCKNAM, a citizen of the United States, and a resident of the city of Philadelphia, county of Philadelphia, and State of Pennsylvania, have invented a new and useful Improvement in Cars, of which the following is a specification.

The object of my invention is to provide a car with large window openings that may be closed by overlapping sashes that move in separate slideways so that one could, under no circumstances, prevent the proper operation of the other, and my invention also includes suitable means for causing one sash to actuate the other when they are raised or lowered. This object is accomplished by my invention, as will more particularly appear hereinafter.

For a more particular description of one embodiment of my invention, reference is to be had to the accompanying drawings, forming a part hereof, in which 'Figure 1 is a sectional view of a car provided with my improvements, the section being taken vertically of the window and about the middle thereof. Fig. 2 is an inside elevation of a portion of the upper sash. Fig. 3 is a view similar to Fig. 2, except that the lower sash is shown instead of the upper. Fig. 4 is an end elevation of the upper sash. Fig. 5 is an end elevation of a portion of the lower sash. Fig. 6 is an enlarged sectional view showing the sashes in their stored positions. Fig. 7 is an enlarged detailed view showing the inter-engagement of the lower sash with the upper when the two are being lowered together. Fig. 8 is a sectional view taken on the line 88 of Fig. 7. Figs. 9 and 10 are perspective views of portions of the upper and lower sashes respectively.

Throughout the various views of the drawings, similar reference characters designate similar parts.

My improved car 1 is provided with the usual stanchions 2, window sill 3, roof 4, letter board 5, head lining 6, inside parting strip 7, an outside parting strip 8, provided with the usual seat 9 on which the upper sash rests. All these parts may be of the usual and conventional form and need no further description.

Above the seat 9 is a small metal parting strip 10 secured by screws or other suitable means to the stanchion 2 which screws pass through perforated ears 11. Extending from the deck rail 12 to the letter board 5 are suitable guides 13, and suspended from the guides 13 by hangers 14, is the upper sash 15 which, when in its lowermost position rests on the step or shoulder 9 and against the parting strip 8 and also the parting strip 10. Extending from the upper edge of the sash 15 and near the outside corner are two hooks 16, only one of which is shown as the two are identical, which hook is curved, as shown in Figs. 1 and 4, and extends upwardly and inwardly a distance approximately the length of sash 15. Near each side edge of the sash 15 is a grooved plate 17 let into a recess in said sash, and this plate 17 is provided with two crossings, upper and lower 18 and 1.9, respectively, the crossing 18 is near the upper end of this plate 17 and the crossing 19 is slightly above the middle. The last crossing is 19, which is located at the bottom of the plate 17.

The lower sash 20 which overlaps the upper sash 15 rests between parting strips 10 and 7, respectively, at its upper end, and throughout the remainder of its length between the parting strips 8 and 7, so that at no portion of its movement does it get into the slideway between the parting stri s 10 and 8. This lower sash 20 is prefera ly larger than the upper sash 15, in the proportion shown, and is provided with the usual cushioning spring 21 and sash lock 22, as well as a projecting lug 23 which extends perpendicular to the outer face of the sash and is adapted to move into the groove in the plates 17 and engage both the crossings 18 and 19 in the manner described below. The stanchion 2 is also provided with suitable bolt holes 24, which are adapted to hold the sash 20 in its various positions, as may be desired.

The windows of my improved car are opened and closed as follows :The sash lock 22 is operated in the conventional manner and the lower sash 20 is then raised and is guided by the spring 21 which presses against the parting strip 7 and causes this lower sash 20 to rub against the parting strip 10, and this continues until the upper end of this sash engages the hook 16,'and then as this sash con tinues its movement the upper sash is raised with it into the position indicated in Fig. 6, where the same are stored in an inclined position between the roof 4 and the head lining 6, the upper sash being supported on the parting strip 10, and hung from the guide 13 by the hanger 14 and the lower sash rests on the head lining 6, where it is supported by the spring 21 and is also held by the lock 22 at its lower end. hen the sashes are taken out of the roof pockets, as shown in Fig. 6, the lower sash is released by operating the lock 22, and is lowered. The sash 15 is then free to move in its proper position under the force of gravity, but if this is insuificient, as it sometimes is, the upper sash 15 is moved from its stored position by the projection 23 on the upper edge of the lower sash which engages first the crossing 18 and causes the upper sash to take a downward movement as long as the crossing 18 and the projection 23 are in contact. At a certain point these two sashes 15 and 20 are separated by the peculiar curvature of the strip 10, and then for an instant the sash 20 is lowered alone until the lug or projection 23 engages the crossing 19, when the two sashes are again moved together. The upper sash 15 is in its correct position for closing the window, or so nearly in this position that it will slide thereto by gravity when the peculiar curvature of the parting strip 10 will again force the lug or projection 23 out of engagement with the crossing and the lower sash is then restored to its original or closed position. If the weight of the sash 15 is insufficient to force it into its closed position by gravity, the projection 23 will engage with the stop 19 before the lower sash 20 reaches a closed position and the two sashes will move simultaneously to their closed positions.

From the foregoing, it is obvious that each sash moves in a slideway which is independent of the other sash, and that it is impossible to have any merging of the slideways. Nor can one sash interfere with the operation of the other, except to cause them to move properly and together, as above set forth.

Various changes may be made in the invention, all of which embody its essential characteristics so that I do not regard it as limited to the precise disclosure herein made but as broad enough to cover all structures that come within the scope of the annexed claims.

1. In a car or similar structure, stanchions provided with two separate slideways, upper and lower sashes moving in said slideways so that each never moves in the slideway of the other, means for causing the lower sash to raise the upper sash when the two are shifted into the storage space in the roof of the car, and means for causing one sash to positively move the other on their downward movement.

2. In a car or similarstructure, stanchions with independent slideways, upper and lower sashes moving in said slideways, so that neither can get in the slideway of the other, means on the upper sash for engaging the lower sash so that when the lower sash is raised, the upper is carried with it, and means on both sashes for causing the lower sash to force the upper sash down when the sashes are removed from the storage chamber.

3. In a car or similar structure, stanchions with separate, curved and widened slideways, upper and lower sashes moving in said slideways so that neither can get into the slideway of the other, a hook on the upper sash adapted to engage the lower sash so that when the lower sash is raised the upper is carried with it and means for causing one sash to positively move the other on their downward movement.

4. In a car or similar structure, stanchions with separate slideways, upper and lower sashes moving in said sildeways, so that neither can enter the slideway of the other, means for causing the lower sash to raise the upper when the sashes are raised into their storage chamber, a recessed plate with crossings let into the inner face of the upper sash and a lug adapted to engage said crossing projecting from the outer face of the lower sash, said lug and crossing being adapted to inter-engage when the sashes are raised, whereby the lower moves the upper.

Signed this 8th day of January, 1907.
